Abstract:
Ubiquitination is a critical biological process in post-translational modification of proteins and involves multiple signaling pathways in protein metabolism, apoptosis, DNA damage, cell-cycle progression, and cancer development. Deubiquitinase, a specific enzyme that regulates the ubiquitination process, is also thought to be closely associated with the development and progression of various cancers. In this article, we systematically review the emerging role of the deubiquitinase ubiquitin-specific peptidase 11 (USP11) in many cancer-related pathways. The results show that USP11 promotes or inhibits the progression and chemoresistance of different cancers, including colorectal, breast, ovarian, and hepatocellular carcinomas, via deubiquitinating several critical proteins of cancer-related pathways. We initially summarize the role of USP11 in different cancers and further discuss the possibility of USP11 as a therapeutic strategy.
Insights
Ubiquitin-specific peptidase 11 (USP11) plays a dual role in cancer, promoting or inhibiting tumor progression and chemoresistance. This review explores USP11
Area of Science:
- Biochemistry and Molecular Biology
- Oncology
- Cellular Biology
Background:
- Ubiquitination is a key post-translational modification regulating protein function, crucial in cellular processes like apoptosis, DNA damage response, and cell cycle progression.
- Deubiquitinases (DUBs) are enzymes that reverse ubiquitination, and their dysregulation is implicated in various cancers.
- Ubiquitin-specific peptidase 11 (USP11) is an emerging DUB with a complex role in cancer biology.
Purpose of the Study:
- To systematically review the multifaceted role of USP11 in the context of cancer-related pathways.
- To elucidate how USP11 influences the progression and chemoresistance of diverse cancer types.
- To discuss the therapeutic potential of targeting USP11 in cancer treatment strategies.
Main Methods:
- Systematic literature review of studies investigating USP11 function in cancer.
- Analysis of USP11's deubiquitinating activity on critical proteins within cancer signaling pathways.
- Comparative analysis of USP11's impact across different cancer types, including colorectal, breast, ovarian, and hepatocellular carcinomas.
Main Results:
- USP11 exhibits context-dependent roles, acting as either an oncogene or tumor suppressor in different cancers.
- USP11 deubiquitinates key proteins involved in cancer progression and chemoresistance mechanisms.
- Evidence suggests USP11 influences the efficacy of chemotherapy in various malignancies.
Conclusions:
- USP11 is a significant regulator of cancer development and progression through its modulation of protein ubiquitination.
- USP11's dual role highlights its complex involvement in oncogenesis and chemoresistance.
- Targeting USP11 presents a promising, albeit complex, therapeutic avenue for diverse cancers.
